Science Experiments for Young Children ▲ Artificial Intelligence Learning
We take the baby to "play" together and plant the seeds of science in the hearts of the children
A small science experiment that can be played at home, only needs the materials of daily life at home
For 5 minutes a day, play with the science around you with your child.
We also have a small experimental group of parent-child science, and parents who care about their children's education can learn together.
Kiki: What are we playing today?
Papa: Let's play a magic trick today.
Kiki: What magic?
Qi Dad: You observe first, and you will know in a moment
Preparation materials:
1 plastic bottle of pure water and 1 bottle of boiling hot water
△ Yibao pure water bottle
Experimental steps:
Experiment 1:
1. Drink the water in the plastic bottle of pure water;
2. Pinch the bottle with your hands or twist it with both hands;
3. Observe whether the shape of the bottle can change, and whether the bottle can become flattened?
Experiment 2:
1. Pour the boiling hot water into the empty plastic bottle of pure water of Yibao;
2. Shake the water in the bottle with your hand a few times;
3. Pour out the hot water poured into the bottle;
4. Quickly close the cap of the bottle of pure water;
5. Pinch the plastic bottle of pure water by hand;
6. Observe whether the shape of the bottle changes at this time, can the bottle be flattened and cannot restore the original shape?
Observed phenomena:
1, pinch the bottle cap of the pure water bottle can not be pinched or screwed and flattened, deformed, after pinching the bottle quickly restore the prototype.
2, pure water plastic bottles, after pouring out hot water to pinch, the bottle becomes flat, and can not restore the prototype of the plastic bottle.
Let's think about it:
Why is it that by pouring hot water into the plastic bottle and then pinching the plastic bottle, the plastic bottle is flattened and the shape has changed?
Qi Dad: Why is the bottle flattened?
Eva: Because you poured hot water into it.
Qi Dad: I was speechless about what Wa said, in fact, what I should ask is why after pouring hot water into the bottle, the bottle can be flattened, and the shape has changed?
Wa: I don't know
Qi Dad: I'll tell you ha.
The principle is not difficult, if you don't understand, don't be afraid, go to primary school and study well, you will understand.
Experimental principle:
After pouring hot water into the plastic bottle, the air inside the bottle and the bottle is heated at the same time, when we pour the hot water out and tighten the cap by hand, the air temperature inside the bottle will be higher than the air temperature outside.
When we pour out the hot water, the bottle cap is opened, the temperature inside the bottle will be reduced, the temperature reduction makes the pressure inside the plastic bottle smaller, the air pressure outside the bottle is greater than the air pressure inside the bottle, plus the pressure we use to pinch the bottle to the bottle, at this time, the bottle is flattened together.
Read the excerpt:
Attention should be paid to the cultivation of children's curiosity about learning! We need to base our children's wishes.
From my own experience in the process of physics study and work, it is very important for the cultivation of hands-on ability! Physics involves intuition coming from the hands. Let the child develop a long-term habit of studying the equipment of a certain kind of thing before doing it.
If you really want your child to become a scientist, a very important place is to let your child do more and have feelings in his hands. The education of children is not just reading, but also very important to let him do it. He wants to play with mud, he wants to catch butterflies, he has to see all kinds of animals and plants, he has to know that diamond is cold, iron is hard, and iron can cut through hands. Such real feelings about our material world may be very important for developing his understanding of science and engineering, which I think may be something that quite a few parents have not noticed. We are living well now, most of the family is only children, and it is very scary to let children do it almost rarely.
Be sure to get your child hands on it.

ps: We take the baby to play science experiments, you can let the baby try it by herself, not just watch the adults do it.

We take the baby to "play" together, play middle school, do middle school, and combine science with entertainment.
If you encounter some confusion in the process of taking a baby and are looking for a solution, you are eager to communicate with the parents of the same frequency.
Welcome to join our [Parent Study Club] learning exchange group, and study and grow with parents who love to learn!
We took the baby together in the "play" middle school, and talked about the challenges and happiness encountered in the process of taking the baby.
